Downloading first n bytes of remote file

[elle]

Hi there,

I need to download FIRST n bytes (n ~ 1024+^2) from remote file (located on the other server than mine). All must be done via fopen or similar functions and served to user via header function in binary mode. No redirection (Location via header allowed !

How's the best technique of that ?

It should be look like the code below. This code I'm using to retrieve data from the tail of the file :

<?php
	
	@ignore_user_abort();
	@set_time_limit(0);

	$name ='http://www.remoteserver.org/file.dat';
	$part_size = 1048576;

	$fp = @fopen($name, 'rb');
	
	@fseek($fp, -$part_size, SEEK_END);

	header("Content-Type: application/octet-stream");
	header('Content-Disposition: attachment; filename="file_part.dat"');
	header("Content-Length: ". $part_size);
	
	@fpassthru($fp);
	exit;

?>

I'm assuming you know n so you could set the header("size: ") to the answer of your equation.

P.S. - it may be "file-size"?

You could use fgets to specify how many bytes to read from the file. May want to look into that

check out the PHP manual for fgets()
